"I think overall it is good, but there are higher quality fabrics which I have previously bought from Alexandra Wood (Bishop’s Stortford, UK), and Piccolo in Naples (https://www.camiceriapiccolo.com/).
However, their shirts are way more expensive. Value wise Tailor Store is great - good quality and affordable!
If you could make shirts with the super high quality fabrics like Piccolo/Alexandra Wood, at an affordable price, that would also be very attractive.
I really like the addition you have now which indicates how transparent a fabric is - that is very helpful when shopping online! Perhaps add the same for how breathable the fabric is, to know if the material is best for for summer/winter/12 months?"
